Love it; I want this too!
It seems natural to use the same headings for every file list, though I realize it is nice if humans who are not me can do theirs differently..

Wish there was ability use one top bar, bar that holds the column titles, as a template for all top bars that show any list of files. Currently one must basically arrange all top bars manually, except in media tree collections, where you can use one collection as a template, but this very same template thinking should be applicable to all file lists.

For example, I prefer to set the main library file list as my template, but I also would like to use the exact same order of columns for all files lists, whether it's collection, search, now playing or any node - that way I'm able to detect the things I need very easily, as the columns stay in exact same order.
